I'm a fan of wordpress. The developer community is really the best feature. Lots of plugins for you to download/try for free that can help improve your users experiences...
I wanted to use wordpress but we don't run mysql on the vps, we use sqlite. I had a friend write me a custom script for my blog instead. I'm very happy with it.
It seems unanimous that wordpress is the winner. I have tested and used many other softwares and the skinning, admin, and functions of wordpress beat the rest. Also the popularity is outstanding, causing frequent updates and more and more plug-ins.
im about to start using wordpress, blogger is a subdomain thing and i dont really like those, if i do use them and they let me use an addon domain, why not lol, i voted wordpress
